CENTRAL-DRAFT LAMP.

SPECIFICATION forming part of Letters Patent No. 395,912, dated January 8, 1889. Application filed May 28, 1888. Serial No. 275,280. (No model.)

To all whom it may concern:

Be it known that I, JOHN C.- MILLER, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in (fcntral-Diaft Lamps; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of IO the same, and which said drawings constitute part of this s pecification, and represent,in

Figure 1, a side view of the lamp, half in vertical section, showing the wick-adjusting device at the lowest point; Fig. 2, the same as Fig. 1, showing the burner removed and the wick-adjuster at its highest elevation; Fig. 3, a top view of the lamp, the burner removed; Fig. 4., a perspective View of the wick and adj listing-sleeve detached, on a reduced scale.

This invention relates to an improvement in that class of lamps in which atubular wick is employed placed around a central tube in the lamp, and so that the said central tube forms a line for the admission of air to the flame at the upper end of the wick to aid in the support of combustion, and commonly called central-draft lamps.

The object of the invention is to provide a OOHVQHiGllt means for introducing, replacing,

or adjusting the wick; and the invention consists in the construction as hereinafter described, and particularly recited in the claim.

A represents the lamp-fount, and B the 3 5 central tube,which opens through the bottom of the fount and around which the wick C is arranged; D, the burner, which may be of anyol' the usual coustrimtions, and is set onto the neck of ihe iount, the openingE through 0 the neck of the [built being concentric with the central tube, but considerably larger in diameter than the said central tube.

Around the outside of the wick a sleeve, .I, is arranged so as to embrace the wick, and

5 so firmly grasp it that an up-and-down movement imparted to the sleeve J will impart a corresponding up-and-dmvu movement to the wick. This sleeve is acommon device in this class ol lamps, and employed as the means for adjusting the wick. It is, however, necessary to remove this sleeve from the lamp in order to attach the wick to it that it may be properly applied to the lamp. It is also desirable that the means for adjusting the wick shall be outside the burner, which, broadly considered, is a common expedient in this class of lamps. The means which I employ for operating the sleeve J consists of arod, K, arranged vertically through the fount outside the burner. This rod extends down and its lower end is turned inward and upward to form an arm, L, inside of but parallel to the rod K. This arm L comes within the circle of the opening E of the neck, so that the rod may be raised and the arm L pass up through the neck, as represented in Fig. 2.

The arm L terminates at its upper end in a socket, M. The sleeve .I is constructed with two cars, N and O, on one side, the ear 0 be ing over the ear N, and distant from each other according to the length of the socket M. The said two ears have an opening through them corresponding to that of the socket M, and so that a headed pin, P, may be introduced through the upper ear, 0, and extend down through the socket M into the ear N, as-shown, thus uniting the sleeve and adjusting-rod, so that as the adjusting-rod is raised or lowered the sleeve will be correspondingly raised and the wick adjusted accordingly.

Above the headed pin 0, I preferably form a projection, R, on the sleeve, which will serve as a stop to prevent the pin from being drawn entirely from the ear 0.

To apply or remove the wick, the burner is 8 5 removed and the wick-adjuster is raised to bring the sleeve .l' above the neck, as represented in Fig. 2. Then the sleeve J may be removed from the adjuster-rod by raising the pin P, as indicated in broken lines. The wick is applied to the sleeve so removed and then replaced and engaged with the adjusting-rod, and by means of the adjusting-rod the wick is moved down into the fount, and may be adjusted to any desired point by raising or lowering the rod. e

The connection between the sleeve and the adjusting-rod is in the form of a hinge, the pin forming the pintle, and so that the sleeve may be turned to the right or left after it is raised from the .fount, as indicated in broken lines, Fig. 3, and so that the wick may be applied or removed without!raking l'ho sloovo from The adjustor-rod, should it ho dosirod so To do.

From tho (on-going it will he uu(l -rshw(l adaptwl lo set, with a rannovablo pin, 1, ilu-ough said oars and socket to form the couihat I do not olaim, broadly, a \\'i:i-k-:uljusior having an adjusi iug-i'od ail'raugod oulsido Hm burner; but
